Rdrg109 created this task. Rdrg109 added projects: Lingua Libre, Wikidata-Query-Service.
TASK DESCRIPTION **Feature summary** (what you would like to be able to do and where): LinguaLibre (Q60024037 <https://www.wikidata.org/wiki/Q60024037>) has a SPARQL endpoint that can be used to query data from that project. The request is to add its SPARQL endpoint to the list of WDQS supported endpoints. The URL for the endpoint is https://lingualibre.org/bigdata/namespace/wdq/sparql **Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution): I wrote the following minimal working example <https://w.wiki/4eDZ> and tried to run it in WDQS SELECT * { SERVICE <https://lingualibre.org/bigdata/namespace/wdq/sparql> { SELECT ?foo { VALUES ?foo {1 2 3}. } } } I got `Server error` with the following message SPARQL-QUERY: queryStr=SELECT * { SERVICE <https://lingualibre.org/bigdata/namespace/wdq/sparql> { SELECT ?foo { VALUES ?foo {1 2 3}. } } } java.util.concurrent.ExecutionException: java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Service URI https://lingualibre.org/bigdata/namespace/wdq/sparql is not allowed at java.util.concurrent.FutureTask.report(FutureTask.java:122) (... 89 more lines ...) As you can see above, the following error is shown `Service URI https://lingualibre.org/bigdata/namespace/wdq/sparql is not allowed`. This happens because the SPARQL endpoint of LinguaLibre is not supported (therefore, it isn't listed in the SPARQL federation endpoints of WDQS <https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual/SPARQL_Federation_endpoints>) **Benefits** (why should this be implemented?): - Wikidata contributors will be able to query LinguaLibre data from WDQS. - LinguaLibre contributors would be able to share LinguaLibre related SPARQL queries by the using WDQS URL shortener. As of the time of this writing, LinguaLibre doesn't have a query service yet, users can write queries in the default interface of Blazegraph Workbench (link <https://lingualibre.org/bigdata/#query>) and AFAIK Blazegraph Workbench doesn't provide a URL Shortener.
